ACTRESS-writer Jennifer Westfeldt channels Woody Allen again for “Ira & Abby,” a more formulaic but still plenty funny and well-cast follow-up to her delightful 2001 hit, “Kissing Jessica Stein.”

Ira (Chris Messina) is a 33-year-old grad student on the Upper West Side, so neurotic and indecisive that his shrink has dropped him after 12 years. His very first trip to the gym ends with his accepting a marriage proposal from the woman selling memberships, the free-spirited Abby (Westfeldt).

“Ira & Abby,” which hilariously climaxes with an intervention involving a roomful of the protagonists’ shrinks (among them Jason Alexander), isn’t as sharply directed as “Jessica Stein,” but it’s still a formidable crowd-pleaser.
